I-Butterfly valve, eyaziwa nangokuthi i-flap valve, i-valve elawulayo enesakhiwo esilula.Amavalvu ovemvane angasetshenziswa ukulawula ukushintsha kwemidiya yamapayipi anengcindezi ephansi.Ivalve uvemvane isebenzisa idiski noma ipuleti uvemvane njengediski, ezungeza i-valve shaft ukuze ivuleke futhi ivale.
Amavalvu ovemvane angasetshenziswa ukulawula ukugeleza kwezinhlobo ezahlukene zoketshezi olunjengomoya, amanzi, isitimu, imidiya eyonakalisayo ehlukahlukene, udaka, uwoyela, insimbi ewuketshezi kanye nemidiya ekhipha imisebe.Idlala kakhulu indima yokusika kanye nokuphonseka epayipini.Ingxenye evulayo nevalayo ye-valve uvemvane iyipuleti uvemvane emise okwediski elizungeza i-eksisi yalo emzimbeni wevalvu ukuze kuzuzwe injongo yokuvula nokuvala noma ukulungisa.
Izici eziyinhloko ze-valve butterfly yilezi: i-torque encane yokusebenza, indawo encane yokufaka nesisindo esincane.Ukuthatha i-DN1000 njengesibonelo, i-valve butterfly cishe i-2 T, kuyilapho i-valve yesango icishe ibe ngu-3.5 T, futhi i-valve uvemvane kulula ukuhlanganisa nemishini ehlukahlukene yokushayela, futhi inokuqina okuhle nokuthembeka.Ukungalungi kwe-valve butterfly evalwe ngenjoloba ukuthi uma isetshenziselwa ukudonsa, i-cavitation izokwenzeka ngenxa yokusetshenziswa okungalungile, okuzobangela ukuxebuka nokulimala kwesihlalo senjoloba, ngakho-ke indlela yokuyikhetha kahle incike ezidingweni zokusebenza. izimo.Ubudlelwano phakathi kokuvulwa kwe-valve uvemvane kanye nezinga lokugeleza ngokuyisisekelo kushintsha ngokulandelana.Uma isetshenziselwa ukulawula ukugeleza, izici zayo zokugeleza nazo zihlobene eduze nokumelana nokugeleza kwamapayipi.Isibonelo, uma amapayipi amabili efakwe ububanzi obufanayo be-valve kanye nefomu, kodwa i-coefficient yokulahlekelwa yamapayipi ihlukile, izinga lokugeleza kwama-valve nalo lizohluka kakhulu.Uma i-valve isesimweni sokudonsa okukhulu, i-cavitation ijwayele ukwenzeka ngemuva kwe-valve plate, engase ilimaze i-valve.Ngokuvamile, isetshenziswa ngaphandle kuka-15 °.Lapho i-valve yovemvane iphakathi nendawo, umumo wokuvula owenziwe umzimba we-valve kanye nengxenye engaphambili yepuleti uvemvane kugxile ku-valve shaft, futhi izinhlangothi zombili zakha izifunda ezihlukene.Ingxenye engaphambili yepuleti uvemvane ngakolunye uhlangothi ihamba ngalapho kugeleza khona amanzi, kanti olunye uhlangothi lunyakaza lapho amanzi agelezayo.Ngakho-ke, uhlangothi olulodwa lomzimba we-valve kanye ne-valve plate yakha ukuvuleka okumise okwe-nozzle, kanti olunye uhlangothi lufana nokuvuleka okumise okwe-throttle.Ijubane lokugeleza ohlangothini lwe-nozzle lishesha kakhulu kunalelo ohlangothini lwe-throttle, futhi ukucindezela okungalungile kuzokwenziwa ngaphansi kwe-valve ohlangothini lwe-throttle, ngokuvamile I-rubber seal izophuma.I-torque yokusebenza ye-valve ye-butterfly iyahlukahluka ngokuvula kanye nokuqondisa kokuvula nokuvala kwe-valve.Kuma-valve e-butterfly enezingqimba, ikakhulukazi ama-valve anobubanzi obukhulu, ngenxa yokujula kwamanzi, i-torque ekhiqizwa umehluko phakathi kwamakhanda angaphezulu naphansi we-valve shaft ayikwazi ukushaywa indiva.Ngaphezu kwalokho, lapho indololwane ifakwe ohlangothini lokungena lwe-valve, kwakheka ukugeleza kwe-bias futhi i-torque izokhula.Uma i-valve iphakathi nendawo, indlela yokusebenza idinga ukuzikhiya ngenxa yesenzo se-torque yokugeleza kwamanzi.
I-Butterfly valve iwuhlobo lwe-valve esebenzisa uhlobo lwe-disc okuvula nokuvala izingxenye ukuze ijikele emuva naphambili cishe ngo-90° ukuze ivule, ivale noma ilungise ukugeleza kokuphakathi.I-Butterfly valve ayinayo nje isakhiwo esilula, usayizi omncane, isisindo esincane, ukusetshenziswa kwezinto eziphansi, usayizi omncane wokufaka, i-torque encane yokushayela, ukusebenza okulula nokushesha, kodwa futhi inomsebenzi omuhle wokulawula ukugeleza kanye nezici zokuvala nokuvala ngesikhathi esifanayo.Enye yezinhlobo zama-valve ezisheshayo.Ama-valve ovemvane asetshenziswa kakhulu.Izinhlobonhlobo kanye nenani lokusetshenziswa kwayo zisakhula, futhi ithuthukela ekushiseni okuphezulu, ukucindezela okuphezulu, ububanzi obukhulu, ukuvalwa okuphezulu, impilo ende, izici ezinhle kakhulu zokulungisa, kanye nokusebenza okuningi kwe-valve.Ukuthembeka kwayo nezinye izinkomba zokusebenza sezifinyelele izinga eliphezulu.
I-valve uvemvane ivamise ukuba ngaphansi kuka-90° ukusuka ekuvulekeni kuya ekuvalekeni ngokugcwele.I-valve uvemvane nentonga yovemvane azinawo amandla okuzivalela.Ukuze ubeke ipuleti levemvane, isinciphisi segiya lezikelemu kufanele sifakwe entweni yevalvu.Ukusetshenziswa kwe-worm gear reducer akugcini nje ukuvumela ipuleti le-butterfly libe nekhono lokuzivala, lenza ipuleti le-butterfly lime kunoma iyiphi indawo, kodwa futhi lithuthukisa ukusebenza kwe-valve.Izici ze-valve ye-butterfly ekhethekile yezimboni: ukumelana nokushisa okuphezulu, ububanzi bokucindezela okuphezulu, ububanzi obukhulu be-valve, umzimba we-valve wenziwe nge-carbon steel, futhi indandatho yokuvala yepuleti ye-valve yenziwe ngendandatho yensimbi esikhundleni se-valve. indandatho yerabha.Amavalvu ovemvane anezinga eliphezulu lokushisa okuphezulu akhiqizwa ngamapuleti ensimbi ashiselayo futhi asetshenziselwa kakhulu imigudu yegesi ephumayo kanye namapayipi egesi emidiya yezinga lokushisa eliphezulu.
